Please try rebooting both your router and Sure signal at the same time, using the follow steps;

Turn off your router or modem at the plug socket, leave it for 10 seconds and then turn it back on

Wait for the lights on your modem/router to indicate that an Internet connection has been established

Press the reset button on the Sure Signal. For further details on this process, please follow the reset procedure.

If this doesn't work, and you're using a BT Home Hub 4 or 5 please make sure that Smart Setup is disabled in your router settings. You can do this by logging into the router. BT will be able to give advice on doing this if needed.

Once these steps have been followed, if the Sure Signal is still not connecting, please try a new Ethernet cable.

If no lights are showing on the Sure Signal V2, then I would recommend calling Vodafone Customer Service via 191 or Live Chat through the website as there appears to be a fault with the device and the technical team might be able to assist you.

Thanks for your help. I registered the box this morning after your message, but I still only have the red power light. The other 2 lights flicker on for a split second upon turning it on, then go out out. They don't seem to attempt to try and connect. What's the next stage please?
